I have a curved arrow in Illustrator. I've separated the arrow head and arrow body. I've made a central path along the body to use as a positional path for the arrowhead in AE. All works fine except that I'd like to keep the arrowhead perpendicular to the curved arrow body. Is this an expression based solution? I know I could just use rotation but I'm guessing there's a more elegant solution with less keyframes.
